It doesn't seem to mention the works of the Indian mathematicians from Kerala, India on calculus. I think their work predated that of Newton and Leibniz.
> Their work, completed two centuries before the invention of calculus in Europe, provided what is now considered the first example of a power series (apart from geometric series).[2] However, they did not formulate a systematic theory of differentiation and integration, nor is there any direct evidence of their results being transmitted outside Kerala.
I agree! Our (subconscious?) arrogance of our intellect always biases the way we look at our ancestors. If we could just be more humble, we would probably be seeing more of what's there.
